I am not of course maintaining that Theology, even before you believe it, is totally bare of aesthetic value. But I do find it superior in this respect to most of its rivals. Consider for a few moments the enormous aesthetic claim of its contemporary rival -- what we may loosely call the Scientific Outlook, the picture of Mr Wells and the rest. Supposing this to be a myth, is it not one of the finest myths which human imagination has yet produced? The play is preceded by the most austere of all preludes: the infinite void, and matter restlessly moving to bring forth it knows not what. Then, by the millionth millionth chance - what tragic irony - the conditions at one point of space and time bubble up into that tiny fermentation which is the beginning of life. Everything seems to be against the infant hero of our drama - just as everything seems against the youngest son or ill-used stepdaughter at the opening of a fairy-tale. But life somehow wins through. With infinite suffering, against all but insuperable obstacles, it spreads, it breeds, it complicates itself: from the amoeba up to the plant, up to the reptile, up to the mammal. We glance briefly at the age of monsters. Dragons prowl the earth, devour one another and die. Then comes the theme of the younger son and the ugly duckling once more. As the weak, tiny spark of life began amidst the huge hostilities of the inanimate, so now again, amidst the beasts that are far larger and stronger than he, there comes forth a little naked, shivering, cowering creature, shuffling, not yet erect, promising nothing: the product of another millionth millionth chance. Yet somehow he thrives. He becomes the Cave Man with his club and his flints, muttering and growling over his enemies' bones, dragging his screaming mate by her hair (I could never quite make out why), tearing his children to pieces in fierce jealousy till one of them is old enough to tear him, cowering before the terrible gods whom he has created in his own image. But these are only growing pains. Wait till the next Act. There he is becoming true Man. He learns to master nature. Science comes and dissipates the superstitions of his infancy. More and more he becomes the controller of his own fate. Passing hastily over the present (for it is a mere nothing by the time-scale we are using), you follow him on into the future. See him in the last Act, though not the last scene, of this great mystery. A race of demigods now rule the planet - and perhaps more than the planet - for eugenics have made certain that only demigods will be born, and psycho-analysis that none of them shall lose or smirch his divinity, and communism that all which divinity requires shall be ready to their hands. Man has ascended his throne. Hence forward he has nothing to do but to practice virtue, to grow in wisdom, to be happy. And now, mark the final stroke of genius. If the myth stopped at that point, it might be a little pathetic (sic). It would lack the highest grandeur of which human imagination is capable. The last scene reverses all. We have the Twilight of the Gods. All this time, silently, unceasingly, out of all reach of human power, Nature, the old enemy, has been steadily gnawing away. The sun will cool - all suns will cool - the whole universe will run down. Life (every form of life) will be banished, without hope of return, from every inch of infinite space. All ends in nothingness, and "universal darkness covers all." The pattern of myth thus becomes one of the noblest we can conceive. It is the pattern of many Elizabethan tragedies, where the protagonist's career can be represented by a slowly ascending and then rapidly falling curve, with its highest point in Act IV. You see him climbing up and up, then blazing in his bright meridian, then finally overwhelmed in ruin.
Such a world-drama appeals to every part of us. The early struggles of the hero (a theme delightfully doubled, played first by life, and then by man) appeals to our generosity. His future exaltation gives scope to a reasonable optimism; for the tragic close is so very distant that you need not often think of it--we work with millions of years. And the tragic close it self just gives that irony, that grandeur, which calls forth our defiance, and without which all the rest might cloy. There is a beauty in this myth which well deserves better poetic handling than it has yet received: I hope some great genius will yet crystallize it before the incessant stream of philosophic change carries it all away. I am speaking, of course, of the beauty it has whether you believe it or not. There I can speak from experience: for I, who believe less than half of what it tells me about the past, and less than nothing of what it tells me about the future, am deeply moved when I contemplate it. The only other story--unless, indeed, it is an embodiment of the same story--which similarly moves me is the Nibelung's Ring (Enden sah ich die Welt!).
We cannot, therefore, turn down Theology, simply because it does not avoid being poetical. All world views yield poetry to those who believe them by the mere fact of being believed. And nearly all have certain poetical merits whether you believe them or not. This is what we should expect. Man is a poetical animal and touches nothing which he does not adorn.
There are, however, two other lines of thought which might lead us to call Theology a mere poetry, and these I must now consider. In the first place, it certainly contains elements similar to those which we find in many early, and even savage, religions. And those elements in the early religions may now seem to us to be poetical. The question here is rather complicated. We now regard the death and return of Balder as a poetical idea, a myth. We are invited to infer thence that the death and resurrection of Christ is a poetical idea, a myth. But we are not really starting with the datum "Both are poetical" and thence arguing "Therefore both are false". Part of the poetical aroma which hangs about Balder is, I believe, due to the fact that we have already come to disbelieve in him. So that disbelief not poetical experience, is the real starting point of the argument. But this is perhaps an over-subtlety, certainly a subtlety, and I will leave it on one side.
What light is really thrown on the truth or falsehood of Christian Theology by the occurrence of similar ideas in Pagan religion. I think the answer was very well given a fortnight ago by Mr. Brown. Supposing, for purposes of argument, that Christianity is true, then it could avoid all coincidence with other religions only on the supposition that all other religions are one hundred per cent erroneous. To which, you remember, Professor Price replied by agreeing with Mr. Brown and saying: "Yes. From these resemblances you may conclude not 'so much the worse for the Christians' but 'so much the better for the Pagans'." The truth is that the resemblances tell nothing either for or against the truth of Christian Theology. If you start from the assumption that the Theology is false, the resemblances are quite consistent with that assumption. One would expect creatures of the same sort, faced with the same universe, to make the same false guess more than once. But if you start with the assumption that the Theology is true, the resemblances fit in equally well. Theology, while saying that a special illumination has been vouchsafed to Christians and (earlier) to Jews, also says that there is some divine illumination vouchsafed to all men.

The picture so often painted of Christians huddling together on an ever narrower strip of beach while the incoming tide of "Science" mounts higher and higher, corresponds to nothing in my own experience.
That grand myth which I asked you to admire a few minutes ago is not for me a hostile novelty breaking in on my traditional beliefs. On the contrary, that cosmology is what I started from. Deepening distrust and final abandonment of it long preceded my conversion to Christianity. Long before I believed Theology to be true I had already decided that the popular scientific picture at any rate was false. One absolutely central inconsistency ruins it; it is the one we touched on a fortnight ago. The whole picture professes to depend on inferences from observed facts. Unless inference is valid, the whole picture disappears. Unless we can be sure that reality in the remotest nebula or the remotest part obeys the thought--laws of the human scientist here and now in his laboratory-in other words, unless Reason is an absolute--all is in ruins. Yet those who ask me to believe this world picture also ask me to believe that Reason is simply the unforeseen and unintended by-product of mindless matter at one stage of its endless and aimless becoming. Here is flat contradiction. They ask me at the same moment to accept a conclusion and to discredit the only testimony on which that conclusion can be based. The difficulty is to me a fatal one; and the fact that when you put it to many scientists, far from having an answer, they seem not even to understand what the difficulty is, assures me that I have not found a mare's nest but detected a radical disease in their whole mode of thought from the very beginning. The man who has once understood the situation is compelled henceforth to regard the scientific cosmology as being, in principle, a myth; though no doubt a great many true particulars have been worked into it.
After that it is hardly worth noticing minor difficulties. Yet these are many and serious. The Bergsonian critique of orthodox Darwinism is not easy to answer. More disquieting still is Professor D. M. S. Watson's defence. "Evolution itself," he wrote, "is accepted by zoologists not because it has been observed to occur or... can be proved by logically coherent evidence to be true, but because the only alternative, special creation, is clearly incredible." Has it come to that? Does the whole vast structure of modern naturalism depend not on positive evidence but simply on an a priori metaphysical prejudice. Was it devised not to get in facts but to keep out God? Even, however, if Evolution in the strict biological sense has some better grounds than Professor Watson suggests -- and I can't help thinking it must -- we should distinguish Evolution in this strict sense from what may be called the universal evolutionism of modern thought. By universal evolutionism I mean the belief that the very formula of universal process is from imperfect to perfect, from small beginnings to great endings, from the rudimentary to the elaborate: the belief which makes people find it natural to think that morality springs from savage taboos, adult sentiment from infantile sexual maladjustments, thought from instinct, mind from matter, organic from inorganic, cosmos from chaos. This is perhaps the deepest habit of mind in the contemporary world. It seems to me immensely implausible, because it makes the general course of nature so very unlike those parts of nature we can observe. You remember the old puzzle as to whether the owl came from the egg or the egg from the owl. The modern acquiescence in universal evolutionism is a kind of optical illusion, produced by attending exclusively to the owls emergence from the egg. We are taught from childhood to notice how the perfect oak grows from the acorn and to forget that the acorn itself was dropped by a perfect oak. We are reminded constantly that the adult human being was an embryo, never that the life of the embryo came from two adult human beings. We love to notice that the express engine of today is the descendant of the "rocket;" we do not equally remember that the " Rocket" springs not from some even more rudimentary engine, but from something much more perfect and complicated than itself-namely, a man of genius. The obviousness or naturalness which most people seem to find in the idea of emergent evolution thus seems to be a pure hallucination.
On these grounds and others like them one is driven to think that whatever else may be true, the popular scientific cosmology at any rate is certainly not. I left that ship not at the call of poetry but because I thought it could not keep afloat. Something like philosophical idealism or Theism must, at the very worst, be less untrue than that. And idealism turned out, when you took it seriously, to be disguised Theism. And once you accepted Theism you could not ignore the claims of Christ. And when you examined them it appeared to me that you could adopt no middle position. Either he was a lunatic, or God. And He was not a lunatic.
